很多人认为 “猫和狗” 是天敌。如果这两种动物打起架来，那会是怎样的一番情景呢?表达 “fight like cat and dog 像猫和狗一样打架” 形容 “人与人之间的争吵非常激烈、吵得不可开交”。
My older brother and I used to fight like cat and dog when we were younger. We argued all the time.
We can't let them work together; they just fight like cat and dog. They never agree on anything.
The two students didn’t like each other– they were always fighting like cat and dog. Their arguments disturbed the other students, so they were often asked to leave their class by the teacher.
